If you ate the spaghetti, then the dream shows your worries towards particular relationships you are in at the moment. Maybe the person you are in love with or have a very strong bond with him is not the one who he pretends to be. Make sure you pay attention to the words he says to you and generally the way he acts with you, as the spaghetti in a dream shows the dishonesty and falseness.
Dream dictionary: tti dream meanings
Dreaming of confetti obstructing your view in a crowd of merry-makers, denotes that you will lose much by first seeking enjoyment, and later fulfil tasks set by duty.
The dream, in which you see the confetti, denotes to acceptance, luck and joy. Perhaps you received the great achievements in your waking life through the hard work and efforts that you put in. This time of your life everything will go upside down, positively. On the other hand, the dream may indicate the lack of seriousness within your personality. The dream may suggest you to look at things more earnestly.
